HS v2022 Code: 730441

About steel, stainless; cold-drawn or cold-rolled (cold-reduced), tubes and pipes of circular cross-section

HS code 730441 covers the import and export of stainless steel tubes and pipes of circular cross-section that have been cold-drawn or cold-rolled (cold-reduced). This industry plays a crucial role in the global manufacturing and construction sectors, providing essential components for a wide range of applications, from industrial equipment to infrastructure projects. The demand for these specialized steel products is driven by their superior corrosion resistance, durability, and versatility, making them an indispensable material in various industries.

Production process

The production of stainless steel tubes and pipes under HS code 730441 typically involves a multi-step process. First, stainless steel billets or ingots are heated and then passed through a series of rolling mills to reduce the thickness and shape the material into the desired tube or pipe form. The cold-drawing or cold-rolling process further refines the dimensions and surface finish of the final product, enhancing its mechanical properties and dimensional accuracy.

Production inputs

The main inputs required for the production of HS code 730441 items include high-quality stainless steel alloys, such as austenitic, ferritic, or martensitic grades. Specialized rolling and drawing equipment, as well as cutting and finishing tools, are also essential for the manufacturing process. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities.

Production outputs

The primary output of HS code 730441 is stainless steel tubes and pipes of circular cross-section, which are widely used in various industries. These products may be further consumed by other HS codes, such as 842139 Filtering or purifying machinery and apparatus for gases, 841940 Distilling or rectifying plant, and 848180 Taps, cocks, valves, and similar appliances for pipes, boiler shells, tanks, vats, or the like, including pressure-reducing valves and thermostatically controlled valves.

Revisions to 730441
